<b>Q1: How to integrate Universal Viewer into popular file managers?</b>

<p>
<b>A:</b>

<ul>
<li><b>Windows Explorer</b>
  <p>
  In UV open "Options -- Configure" dialog, 1st tab, check the option "Show Explorer context menu item".
  (Under Vista/Win7 you may need to run UV as Administrator.)
  This will add UV item to Explorer context menu.

<p>
<li><b>Total Commander</b>
  <p>
  "Configuration -- Options" dialog, "Edit/View" tab, check "External Viewer" and enter path
  to Viewer.exe into "Default:" field. If this path contains spaces, double-quote it first.
  <p>
  This will assign Viewer to F3 key.
  <p>
  Also you may create toolbar button to call Viewer with several files selected on TC file panel.
  Drag Viewer.exe file onto TC toolbar empty space, new toolbar button will be created. Rigth-click it,
  select Change and in the Parameters field enter "@%UL" (with quotes).

<p>
<li><b>FAR Manager</b>
  <p>
  "Options -- Viewer settings" dialog, check "Use for Alt+F3" and
  enter path to Viewer.exe with additional macros into "Viewer command:" field:<br>
  <font face="Courier">
  "C:\Program Files\Universal Viewer\Viewer.exe" "!\!.!"
  </font>
  <p>
  This will assign Viewer to Alt+F3 key.
  <p>
  Also you may pass to UV list of files selected on FAR file panel. To do this, change the value of
  "Viewer command:" field like this: <br>
  <font face="Courier">
  "C:\Program Files\Universal Viewer\Viewer.exe" "@!@AF!"
  </font>

<p>
<li><b>FreeCommander</b>

  <p>
  "Extras -- Settings" dialog, "Programs" tab,
  enter path to Viewer.exe into "External viewer" field.
  <p>
  This will assign Viewer to Shift+F3 key.
  <p>
  To assign Viewer to F3 key, go to "Extras -- Define shortcuts" dialog,
  and for the "File - View external" command set the F3 shortcut.

<p>
<li><b>SpeedCommander</b>

  <p>
  "Extra -- Settings" dialog, "Advanced -- Applications & Internet" tab,
  enter path to Viewer.exe into "Viewer:" field.
  <p>
  This will assign Viewer to F3 key.

</ul>

<b>Q2: I can't view DOC/XLS, ODT/ODS or PDF files. Viewer shows only a blank
page. Is there anything I can do to fix this?</b>

<p>
<b>A1:</b>

<p>
To display DOC/XLS you need to install one of the following:<br>
<ul>
<li><a href="http://office.microsoft.com/" target="_blank">Microsoft Office</a></li>
<li><a href="http://www.uvviewsoft.com/lister_plugins.htm" target="_blank">Lister plugin</a> for DOC/XLS</li>
</ul>

To display ODT/ODS/ODP you need to install one of the following:<br>
<ul>
<li><a href="http://www.openoffice.org" target="_blank">OpenOffice.org</a></li>
<li><a href="http://www.uvviewsoft.com/lister_plugins.htm" target="_blank">Lister plugin</a> for ODT/ODS</li>
</ul>

To display PDF you need to install one of the following:<br>
<ul>
<li><a href="http://www.adobe.com" target="_blank">Adobe Reader</a></li>
<li><a href="http://www.foxitsoftware.com" target="_blank">Foxit Reader</a></li>
<li><a href="http://www.uvviewsoft.com/lister_plugins.htm" target="_blank">Lister plugin</a> for PDF</li>
</ul>

<p>
<b>A2</b>: If the first answer doesn't help,
i.e. you have needed Office applications installed
but the window is still blank in Internet mode,
try to enable option "Multimedia -- Internet -- Try to open unknown file types".

<b>Q3: What are the limits for files sizes?</b>

<p>
<b>A:</b>
UV can show, in Text/Binary/Hex/Unicode modes, files of any size.
You can quickly scroll huge files in mentioned view modes,
as UV holds in memory only small amount of file data (approximately 120-180 Kb),
and not the whole file contents.

<p>
But you cannot open huge files in RTF/UTF-8 mode and (usually) in Plugins mode,
because RichEdit control and most of plugins try to load the whole file contents
and this will be very slow and will fail.

<b>Q4: If a link in a local HTML file opens a page from the Internet within Universal Viewer,
could there be any security concerns? The reason I ask this question is because we are constantly
hearing stories about security flaws in this or that browser.</b>

<p>
<b>A:</b> Security concerns in UV are almost the same as in Internet Explorer (with current settings).
UV uses web control based on code and settings of current installation of MSIE.

<p>
So If MSIE has a flaw and you don't want to open a page with it,
you shouldn't also open the link to that page in UV. To prevent this, I recommend to check the option
"View -- Internet -- Offline browsing", which prevents online content to be opened.
Note that some links can be setup to be opened in a separate MSIE window, and this option won't affect them.

<b>Q5: Can the Flash animation be played not in the full window?</b>

<p>
<b>A:</b> By default Flash animation is played in Internet mode, in MSIE window.
You may change this to play it in different way, where you can affect Flash picture size:

<ul>
<li> using Windows Media Player. Open configuration dialog, and on the first tab move "swf" file extension
from Internet list to Multimedia list. Then on the second tab check "Windows Media Player 9.0" mode. </li>
<li> <a href="http://www.uvviewsoft.com/lister_plugins.htm" target="_blank">using one of the Lister plugins</a>. </li>
</ul>

<a name="Q6"></a>
<b>Q6: Why some UTF-8 encoded texts are not shown?</b>

<p>
<b>A:</b> In older versions (older than 1.5.9.0) UV required presence of UTF-8 signatures in the file.
In newer versions this is not required, but note:

<ul>
<li> UTF-8 is not supported under Windows 9x.
<li> UTF-8 texts without signatures will not be autodetected, so you'll have to manually set
"RTF/UTF-8" view mode.
</ul>

<b>Q7: Word/Excel documents are sometimes opened in a new window...</b>

<p>
<b>A:</b> This is a known problem with MS Office, it sometimes can be fixed
by applying the following .REG file. Save the following text to a new file,
name it "Fix.reg" and double-click it in Explorer:

<p>
<table align="center">
<tr><td class="pre">

<b>Q8: How to change the look of WMP 6.4 control?</b>

<p>
<b>A:</b> The look of Windows Media Player 6.4 control can be changed
to mimic the look of WMP 9.0 (if WMP 9.0+ is installed on your system).
To do this, apply the following .REG file:

<p>
<table align="center">
<tr><td class="pre">
<pre>
REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\ShimInclusionList\VIEWER.EXE]
</pre>
</td></tr>
</table>

<p>
To undo this change, apply the following .REG file:

<p>
<table align="center">
<tr><td class="pre">
<pre>
REGEDIT4

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\ShimInclusionList\VIEWER.EXE]
</pre>
</td></tr>

<b>Q9: When images are get from IrfanView/XnView, the animation doesn't work...</b>

<p>
<b>A:</b>
The IrfanView/XnView intefrace is sending a <u>simple bitmap</u> to the application,
and the animation isn't supported for simple bitmaps.
So to view GIFs with animation you have to use the internal image library
(Hint: use the '4' key to switch between internal library and IrfanView/XnView).

<b>Q10: Does the program have issues with Unicode filenames? </b>

<p>
<b>A:</b>

<ul>
<li> Please don't install application to Unicode-named folder,
     it expects ANSI name.
<li> Unicode filenames may be not supported for: IJL15.dll, IrfanView, plugins.
     Unicode names are loaded using shortnames (8.3) for these cases,
     so you should have shortnames on your OS.
     To check, does your OS have shortnames in a folder, open "cmd.exe" in this folder,
     and then run command "dir /x".
     It should show shortnames for all Unicode names.
</ul>

<b>Q11: How to view CHM files? </b>

<p>
<b>A:</b>

Install the plugin <a href="http://www.totalcmd.net/plugring/htmlview.html" target=_blank>HTMLView</a>.
Then, go to Plugins options dialog (F10 key),
press Configure button for HTMLView, and in the Detect-string field
write the string:<br>
<i>ext:chm</i> <br>

<b>Q12: For Word files, I get message "Cannot init MS Office control"...</b>

<p>
<b>A:</b>
To show Word files, UV can use one of the following:<br>
<ul>
<li> Internet mode. Used if "doc,docx" is added to "Internet" extensions
 list in Options dialog. Not quite good, as you may get
 "Do you want to save this document?" prompts from browser.
<li> MS Office mode. NavPanel add-on is used to support this mode,
so this add-on is needed in registered/trial state. If NavPanel add-on
has expired trial state, you won't be able to initialize MS Office mode
- so the message (question) appears, and you need to register NavPanel.
</ul>
